DraftKings informed buyers on June 9 that its prediction markets enterprise is quickly increasing and the market likes its prospects. In keeping with the corporate’s Kind 8-Ok report, annualized client transaction quantity on the Predictions service in Might 2026 elevated 24% month over month to $1.3 billion, and complete annualized transaction quantity elevated 34% to $3.1 billion. DraftKings inventory rose about 10% in early buying and selling on the information.
DraftKings launched Predictions in December 2025, so these numbers are enormous for a product line that is solely six months previous. Nonetheless, when in comparison with the broader class, firms which can be late to market present that predictive-native platforms are already being included into one thing a lot bigger.
On an annualized foundation, this $3.1 billion interprets to roughly $258 million in precise buying and selling quantity in Might. Compared, Kalsi processed $17.9 billion in Might alone.
The distinction between DraftKings’ $258 million and the projected market’s $24 billion.
Prediction markets let you commerce contracts tied to the result of future occasions, from elections and inflation knowledge to sports activities outcomes and cryptocurrency costs. Every contract pays $1 if the occasion happens and $0 if the occasion doesn’t happen, with costs in between performing like a stay likelihood gauge. A contract buying and selling at 65 cents signifies that merchants collectively give the result a 65% likelihood.
As with shares, you may maintain onto them till the occasion is resolved or promote them early on the present worth. Attributable to their construction, these platforms primarily function like monetary exchanges, with order books created and costs consistently fluctuating. It is a large a part of why so many firms are speeding to become involved.
This can even assist decipher a few of the accounting included within the DraftKings announcement. “Annualized” signifies that an organization’s month-to-month exercise is multiplied by 12. It is a normal option to present momentum, however the headline quantity is 12 instances bigger than what truly occurred.
Strip that out, and DraftKings processed about $258 million in transactions in Might. Established platforms function on a totally completely different scale. In keeping with a Pew Analysis Middle evaluation, the mixed month-to-month buying and selling quantity of the 2 largest firms, Calci and Polymarket, rose from lower than $5 billion in September 2025 to about $24 billion in April 2026.
Might knowledge launched after the Pew survey confirmed the 2 platforms shifting in reverse instructions. Kalshi recorded a document of 9 consecutive months at $17.91 billion, whereas Polymarket’s gross sales fell for two consecutive months to $7.08 billion.
For comparability, all authorized sportsbooks within the U.S. mixed generated roughly $14 billion in wagers per thirty days all through 2025. The prediction market class that DraftKings simply entered is already shifting more cash than the trade during which DraftKings was born.
Nonetheless, it is necessary to notice that every platform measures quantity otherwise. Robinhood skips the greenback totally and reviews the variety of contracts traded. This quantity sounds astronomical, since contracts most frequently price lower than $1 per contract.
The corporate’s CEO, Vlad Tenev, mentioned greater than 12 billion contracts had been traded on the platform in 2025, predicting that the enterprise might ultimately develop its annual buying and selling quantity to “trillions”, whereas Deutsche Financial institution has counted greater than 16 billion contracts to this point by 2026. Though the size is completely different, all variations of the calculation result in the identical consequence. DraftKings’ buying and selling quantity in Might is about the identical as Mr. Calci’s buying and selling quantity in every week.
Sports activities is the driving power driving all of this ahead, which explains why sportsbooks don’t have any selection however to emerge. As reported by CryptoSlate, sports activities alone account for roughly 80% of Kalsi’s buying and selling quantity, and when mixed with politics and cryptocurrencies, sports activities have pushed roughly 91% of Kalsi’s exercise and 90% of Polymarket’s exercise since July 2024.
DraftKings has timed its disclosures within the days earlier than the 2026 World Cup and instantly after the NBA Finals, with one estimate pegging potential World Cup prediction market exercise at $2.5 billion.
What sportsbooks are actually searching for
All sides on this battle has weapons that the opposite would not. Sportsbooks convey thousands and thousands of present clients, well-known manufacturers, cost infrastructure, enormous advertising and marketing budgets, and years of expertise in pricing stay odds.
Prediction-native platforms convey a deep pool of merchants able to be on the opposite facet of any contract, a wider menu of occasions, and importantly, a authorized construction that enables merchants to function the place sportsbooks can’t.
DraftKings CEO Jason Robbins informed buyers the corporate intends to determine itself as a pacesetter in sports activities forecasting by the tip of the 12 months, elevating his estimate of the corporate’s complete addressable market from $55 billion to $80 billion.
This authorized construction is your complete purpose this class exists. Sports activities betting in the USA is managed on a state-by-state foundation, and every sportsbook requires a license in each state during which it operates. Occasion contracts comply with a distinct authorized route. Occasion contracts are labeled as derivatives, that are monetary devices overseen solely by the CFTC, the identical regulator that oversees oil and corn futures. A federal license signifies that one approval covers your complete nation. As such, DraftKings launched Predictions in 38 states, together with states the place on-line sports activities betting remains to be unlawful.
Whether or not that route survives is now the central authorized battle within the American playing world. A federal appeals courtroom dominated on April 6 that Carsi’s sports activities contracts seemingly fall below unique federal jurisdiction and are shielded from New Jersey playing enforcement.
Ten days later, one other appellate courtroom listening to the Nevada case appeared inclined to rule in the wrong way. Diverging courts normally require the Supreme Court docket to settle the case, and prediction market merchants themselves imagine there’s a 64% probability the excessive courtroom will take up the case by the tip of the 12 months.
In the meantime, enforcement continues to escalate in each instructions. The CFTC sued Arizona, Connecticut, and Illinois in April to dam its pursuit of Calci and Polimarket, courts in Maryland and Massachusetts sided with state regulators, Calci faces greater than a dozen federal lawsuits, and a report from CryptoSlate reveals related tensions are taking part in out abroad, from person surveys in South Korea to platform blocks in Brazil.
The following notable resolution comes from the Sixth Circuit. There, Mr. Carsi is interesting a ruling that contradicts the one in Ohio, and the coalition in opposition to Mr. Carsi and the corporate continues to develop.
Former CFTC Chairman Gary Gensler, who led the CFTC Fee when Dodd-Frank was launched in 2010, filed a courtroom transient on June 11 arguing that Congress by no means meant for his company to grow to be a nationwide sports activities betting regulator and that sports activities betting just isn’t a swap below the legislation he helped write.
He filed together with the American Gaming Affiliation, 30 Native American tribes, the Indian Gaming Affiliation, and Higher Market. A parallel case in Massachusetts has already had 38 state attorneys common lined up behind the state.
This division extends to the sportsbook trade itself. DraftKings and FanDuel left AGA in November 2025, days earlier than DraftKings launched Predictions, after the trade group transitioned to members working prediction markets. The affiliation is now arguing in courtroom that the product DraftKings has simply constructed is illegitimate playing.
Earlier than you are taking these numbers at face worth, there’s another factor price understanding. That’s, buying and selling quantity is how a lot cash is traded. income It is a small slice that the platform holds. As a result of this slice comes from a charge of some cents per contract, the precise income earned on a $1 billion deal could solely be a number of million {dollars}.
The trade as an entire incurred about $31 million in charges in April, of which Polymarket recovered $29 million as its merchants positioned bigger bets, despite the fact that it lagged properly behind Calci in buying and selling quantity. DraftKings hasn’t disclosed how a lot revenue Predictions’ quantity will generate, so the $3.1 billion run price solely measures traction and leaves the query of revenue open.
DraftKings prediction market development has been important, with a 34% month-to-month enhance being a price-moving quantity. However extra importantly, conventional sportsbooks comply with a class they did not invent. In that class, Calci, Polymarket and Robinhood have already proven that occasion contracts can generate billions of {dollars} a month, and have spent years constructing each the depth of their offers and the authorized arguments to defend them.
Whether or not DraftKings can convert sports activities viewers into exchange-style merchants earlier than these platforms grow to be too liquid to seize is an open query, and the reply will say lots about whether or not the sportsbook mannequin will take up or be absorbed by the prediction market.
